BOXING FOR GUTTERS.

srEoIFIoATIoN forming part of Letters Patent No. 670,448, dated March26,1901. Application fine April 14,1899. derialNo. 713,054. \No model.)

T0 obi/Z whom it may concern:

Be it known that I, HENRY GAUOH, a citizen of the United States,residing at Rentchlers Station, in the county of St. Clair and State ofIllinois, have in vented certain new and useful Improvementsin Boxingsfor Oolters, &c.; and I do hereby declare the following to be afull,clear, and exact description of the in vention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention relates to boxing for revolving colters or otheranalogous purposes adapted for use on plows, cultivators, or otherdevices where applicable, and the aim of the same is to provide adust-proof bearing having easy-running contact-surfaces, wherein thefriction is materially reduced without the interposition of smallantifrictional devicessuch as balls, rollers, and the like-and onewherein a positive action is insured for the rotative mechanism inoperative relation thereto.

Generally stated, the invention comprises an annular bolt square intransverse section having a double frusto-conical sleeve formed with acentral cylindrical part and fitted thereon, over which are appliedopposite flanged thimbles,each of frusto-conical shape, adapted tosupport the cutter or other device and having a cylindrical openingfitting the cylindrical part of the sleeve, the said bolt beingsupported by suitable pendants or arms.

The invention further consists of the detailed construction andarrangement of parts hereinafter more fully described and claimed.

In the accompanying drawings, Figure 1 is a sectional view of a boxingembodying the invention. Fig. 2 is a detailed perspective view of one ofthe flanged thimbles. Fig. 3 is a similar'view of the doublefrusto-conical sleeve. Fig. 4: is a similar view of the angularconnecting-bolt.

Referring to the drawings, whereinsimilar numerals are utilized toindicate corresponding parts in the several views, the numeral 1designates an angular bolt, which is square and has a head 2 at one endand a screwthreaded opposite end 3, adapted to receive a nut i. Thisbolt is supported by pendants or arms 5, extending from a body-supportand having openings adjacent the terminals l thereof corresponding inangular outline to the contour of the said bolt. Betweenthe pendants orarms 5 a double frusto-conical sleeve 6 is positioned on the said boltand also formed with an opening 7, extending entirely therethrough fromend to end, having a contour similar to that of the bolt. The centralportion of the sleeve 6, as clearly shown by Fig. 3, is cylindrical, asshown at 8, and from thence slopes in opposite directions toward thevends. This sleeve is held in fixed position on the bolt relatively to arotative movement; thereof is of such form that devices applied thereto,which will be presently described, can have an unretarded rotation.

Opposite frusto conical thimbles 9 are slipped over the sleeve 6, andhave tapered openings 10, conforming to the shape of the frusto-conicalconfiguration of the said sleeve on which they bear. The inner portionsof the said thimbles are provided with flanges 11, having a series ofapertures 12 circumferentially formed therein. The thimbles areinitially constructed as to their length in such manner that whenapplied to the sleeve 6 the flanges 11 will stand opposite each otherwith an intervening space between them about approximating the dimensionof the cylindrical portion 8 of said sleeve. Between these flanges acolter 13 or other analogous device is mounted and held in fixedrelation thereto by rivets 14 inserted through the apertures 12. Themode of attaining this securement is not particularly essential, asvarious devices can be utilized for the purpose.

The colter shown is broken away, so that it may be illustrated on alarger scale.

Through a portion of one of the thimbles 9 and an inner part of thecolter or other device 13 an oil-duct 15 15 is formed and controlled bya screw-cap 16. This oil-duct leads to the cylindrical part of thesleeve 6, on which the thimbles and colter or other device haverotation.

There are several modes of assembling the parts specified, one of whichconsists in first securing the thimbles 9 to the colter or other device13 over the sleeve 6, and owing to the double frusto-conical form ofsaid sleeve it will be immovably held in position, and the entire deviceas thus far arranged can then but the exterior surface be insertedbetween the pendants or arms 5 and the angular bolt 1 slipped throughthe angular opening 7 of said sleeve and secured in place by the nut L.The outer ends of the thimbles 9 and the opposite ends of the sleeve 6bear against the inner opposing surfaces of the pendants or arms 5, andin View of their reduced contacting-surface extent, owing to thefrusto-eonical formation thereof, the friction of the ihimbles againstthe pendants or arms will be also very much reduced.

It Will he observed that a completely dustproof boxing is provided and acenter 'un of movement of the colter at all times maintained,irrespective of any wear that may ensue. Theoppositefrusto-conicalbearing-surfaces of the sleeve 6 also set up an easy-ruuning movementfor the thimbles 9, in vieW of the convergence, which affords lessresistance and material decrease in friction as compared with a straightcylindrical hearing. The parts are also capable of modification in sofar as the proportions, dimensions, and minor details of constructionare concerned Without departing from the scope of the invention orsacrificing, any advantages thereof.

Having thus described the invention, what is claimed as new is-- Thecombination of the pendant arms, a bolt square in transverse section,having a head atone end, fitting in correspondingopenings in the armsand having a screw-thread at the other end, a nut for securing the bolt,an integral double frusto-conical sleeve having a cylindrical centralpartand mounted on the bolt and fitted between the arms, a eutter havinga cylindrical opening, fitted to the cylindrical part of the sleeve, andformed with the inner end of an oil-duct leading onto the cylindricalcentral part of the sleeve, frustoconical thimbles fitted between thearms and having flanges secured to the cutter, one of the lhimbles beingformed at its juncture with its flange with the outer part of theinclined oil-duct which registers with the inner part thereof, and ascrew-cap closing the oil-duct.

In testimony whereof I affix my signature in presence of two witnesses.

HENRY GAUOH.
